To all whom it may concern: Be it known that we, JOHN A; Gnome son andJessie M. FLIOKINGER, citizens of the United States. residing atKushequa, in the county of McKean'and State of Pennsylvania, have,invented certain new and useful Improvements in Brick and BlockMachines; and we do declare the following to be full, clear, and exactdescription of the invention, such as will enable other skilled th artto which it appertuius to make and use the same. This invention relatesto plastic block apparatus, and more especially to such as have a singlemold with a cam-operated plunger and a cutter-rotating on thelongitudinal axis of the machineyand the-object of the same is toproduce improvements in a ma-. chine of this character. This and otherobjects are accomplished by the construction hereinafter more fullydescribed and claimed and as shown in the drawings wherein- Figure 1 isa side elevation and Fig. 2 a

plan view of the machine complete; Fig. 3'

is a cross sectionon the line 3-3 of Fig. .1, and F igs. 4C, 5 and 6 aresections on the lines 4.--- l, 55 and 66 of Fig. 2; Fig. 7 is a front:elevation, and Fig. 8 a side View of the wire tightener on an enlargedscale, Fig. 9 is a side view thereof with the nearer pawl removed, andFig. 10 is a section on the line 10 -10 of Fig.0; Fig. 11 is an enlargedperr-pective section ofthe gear ring and the outer end wall of thecutting mechanism,

.speciive (let: ii of the boil] g taken about on the line 111. 1 of Fig.(3 and on a larger scale; Fig. 12 1s a perthe cut-o'lt" plate.

in the drawings the numeral 1 desi ates the base of this improvedmachine which at one end -has bearings for the driving shaft whosepulley ills connected with any suit able source of power not shown. Thisshaft is connected as lily-gearing {with the main shaftj also -niouutedon the base and which, with its cams and eccentrlcs, constitute the drivng mechanism 1) of this machine. The

latter consists broadly of theshaping mechanism S including a press box,a plunger.

therein operated from the main, shaft, a hopper, and a die; the cuttingmechanism C to which the die delivers in a manner hereinafter described;and a brake B'interposed 1n the connections between the cuttingmechanism and the driving mechanism so that the former is checked in itsrotation at yoke for reciprocating proper times as will appear below.The de tails of the driving mechanism further than those that have beenmentioned will be amplified below in conjunction with the de scriptionof the other coact.

The shaping mechanism S includes a press parts with which they box 10(see Fig. 4:) having a hopper ll'at is connected by a link 16 with ayoke 17 which is pivoted at its lower end at 18 within the base 1, andwhose side arms carry, loops 19 which are engaged by cams 20 on themainshaft 5. The plunger in the present embodiment of my invention isactuated by two rods 21 whose forward ends are pivoted to the plunger at22 and whose rearward ends are connected with eccentric rings 23 mountedon eccentrics 24 which are fast on the main shaft 5.

The numeral 26 designates a valve located within an air inlet-portthrough the plunger 13 and drawn normally to its seat by means of aspring 27, the valve opening when the plunger is retracted by saldeccen-- t-rics so as to admit air at a proper. time to prevent theretraction of the plunger from drawing the molded plug of clay backwardthrough the die 15.

' It will be well understood by those familiar with thisart that theclay is fed through the hopper 11 when the cutoff plate is retracted,and after a suficient charge has been fed into the box 10 the cams,project the plate 12 and check the feed; and the parts are properlytimed so that next the eccentrics come intonplay and the plunger 13 ismoved'forward to compress the charge of clay within the box 10, force 1ttoward and into the tapered extension 14, and

finally eject it through the mouth or die 15 p in the shape of a plugwhich has a cross section corresponding with that of the bricks orblocks to bcproduced and needs only to be out into proper lengths toturn out the finished articles.

The cutting mechanism 0 which operates in conjunction with the partsabove de-i scribed is best shown in detall on Sheet 4 of the drawingsand in connection with the other parts on the "remaining sheets. It

' 6, andthe rod stands at their axis; and

around their peripheries are tracks 34 on which more two rings 35 havingradial gear teeth 36 by means of which the rings are driven in a manneryet to be described. On said rod 33 are loosely mounted collars 37-three in number in the present'instance although of course there mightbe more or less-and these collars are connected by ra- I dial wires 38with rods 39also three in number in the present instance-which connectsaid gear rings 35 so that the latter are forced to revolve in unisonaround the circular end walls and the several wires 38 and collars 37revolve with the rings. The outer end of each wire is by preferenceconnected with a wire tightener best shown in detail in Figs. 7 to 10inclusive. andcomprising a hook member 40 mounted loosely on the rod 39and having a spring 41 within its body pressing radially inward againsta bolt 42 which connects two dogs or pawls 43 whose teeth are therebynormally engaged with those of ratchet wheels 44 that are fast on therod 39. The inner end of each wire 38 is carried by its collar 37 whilethe outer end. is secured to the hook of saidmember 40, and when thewire becomes slack or stretched the tightener' is manipulatedto take upthe looseness thereof. Carried by said axial rod'33 are L:shapedteeth46, four in number in the present instance, properly spaced topermit the three wires 38 to pass between them as the gear rings 35revolve, and the inner faces of the teeth are alined with the inner andlower edges oftwo rectangular openings 50 and 51 made through the walls30 and 31 in line with the outlet end of the die 15. If the latter sitsclose to the inner wall 31, the plug formed by the shaping mechanism maypass therefrom into the cutting mechanism without any intervening means;but by preference 8. table or chute 52 is interposed to prevent thepossibility of the plug of clay getting out of shape between the'timewhen it leaves the die and the time whexf it passes to thecutting-mechanism C.

The-brak B is herein shown as part of the driving mechanism for thecutter.

, Mounted on the main shaft 5 is a mutilated gear wheel 55 which mesheswith a gear pinion 56 mounted on a shaft 57 the latter in the present:case being connected by gears 58 with a counter shaft 59 which in turnis connected by gears 60 with theteeth 36 of the rings 35. The parts areso timed that the toothed portion of the mutilated gear 55 engages thepm1on;.56' so astoactuate the cutting mechanism while the drivingmechopening 50 in the again out into bricks.

anism is retracting the plunger for a second stroke, whereas the blankportion of said mutilated gear 55 passes the pinion 56 and permits thecutting mechanism to remain idle during the forward movement of theplunger and when the plug of clay is being forced through the die intothe cutting mechanism. But in order that the latter shall not under anycircumstances rotate by momentum or even be turned by accident until thefreshly formed plug has been passed into proper position to be cut bythe wires, I make use ofa brake B interposed 'in the connections betweenthe main shaft and the cutting mechanism and herein shown as composed of7a band wheel mounted on the-countersh ft 59 and partly surrounded by aband 66 which constitutes the shoe, the same being connected to one endof a lever 67 pivoted at 68 in the niain frame and having a pin orfinger 69 in its other end. On the main shaft 5 adjacent the mutilatedgear is a cam 70 (shown in dotted lines in Fig. 1) with which the tip ofsaid pin engages; and all these parts are properly proportioned andtimed so that the pin 69 drops into the low portion of the cam 70 andapplies the brake just as the teeth of the mutilated gear'55 pass offthe pinion 56 and its blank portion comes opposite to said pinion. Theapplicati n of the brake at this moment instantly c ecks the rotation ofthe cutting mechanism C just at a time when the'eccentrics are about toproject the rod and move the plunger forward to eject the plug ofcement.

We have not considered it necessary to go into details further than asabove nor to give the proportions and materials of parts, becauseconsiderable latitude in these matters will be permitted to themanufacturer and may be embraced without losing sight of the principleof, our invention.

In operation the clay is fed thr-wt-fgh the hopper in'a manner formingno. part of the present invention, and compressed within the box 10 andejected therefrom by the plunger as described above. Passing over thetable 52 in the form of a plug, it is driven through the openmg51 in theinner wall 31 of the cutting mechanism and across the teeth 46,meanwhile pushing out the bricks or blocks which previous operation, andthese pass out the outer wall 30 onto a suitable table whence'they areconveyedvto the proper point for burning. As soon as the plunger ceasesits begins to recede, the cam 70 releases the brake B and the teeth ofthe mutilated gear 55 come into engagement with the pinion 56 so. thatthe cutting mechanism 0 is rotated one step and the pro ected plug ofclay is wires 39 aroundthe peripheryofthe gear forward movement and Whenthere are three have been cut at the I three such Wires be so many butwhat would assume while the rings :35 as shown, one step. will be onethird of a revolution; but it is clear that there might, be a greater orlesser number than although there should not during the idle moment-sof-the cutting mechanism the plug of clay'can he projected-between twoof the sets of wires 38. Fig. 6 shows the cutting mechanism with one setof the wires passing acrosstheline of the clay plug and between theteeth46, but in Fig. the wires 38 are shoWnin dotted lines in the positionthey plunger is being projected forward. As the latter is re tracted itsvalve 26 opens to admit air to' the interior of the press box 10 whosecut-oli "plate 12 is thenuclosed, and this valve we partial vacuum finduseful. for otherwise a -might be createdthereinor' the plug of claysucked back a trifle through the die 15.

Just as the plunger has reached its rearmost fed 'into thevbox 10'.
